Webpages that use NTLM auth not working in Xibo player for Windows

Player Version

windows 3 R303.0-303

Issue

Webpages using NTLM auth do not load correctly on the player and give a 401.3 forbidden error, but the same URL loads fine in Edge.

The domain has been added to both the AuthServer Whitelist and the Edge Browser Whitelist but it is still not working on the player.

Running ProcMon to determine what the XiboPlayer is doing, it appears to still be launching CefSharp instead of the Edge browser like it is supposed to be based on what the Edge Browser Whitelist is supposed to do when configured.
